Title: Improvements in or relating to electrical systems for the automatic control of volume, frequency or the like
IPC: H03J7/14
Filed: 1946-11-27
Abstract: 626,088. Automatic tuning and volume control. PHILIPS LAMPS, Ltd. Nov. 27, 1946, No. 35196. Convention date, June 1, 1943. [Class 40 (v)] A valve to which a control voltage is applied for such a purpose as varying its gain or output capacitance is arranged to present at its input a capacitance of such a value as to appreciably vary the effective time constant of the control voltage smoothing circuit in accordance with the value of the control voltage by feeding back a voltage to the grid of the valve which is in quadrature with the anode voltage. The Figure shows a reactance valve circuit, provided with the usual grid anode coupling network made up of a blocking capacitor 32 and a phase-shift network 33, 34, which is modified by connecting a large capacitor 36 between anode and grid so that the valve presents an input capacitance which is of the same order as the smoothing capacitor 4, and varies with the grid bias. Chokes 31 and 35 are provided to prevent the capacitors 4 and 36 from upsetting the high-frequency operation of the circuit. This method of varying the smoothing circuit time constant may be used with an arrangement in which the control voltage varies the inductance of an inductor by varying the current through a valve having a saturation control winding in its anode circuit, Fig. 1 (not shown). In the Specification as open to inspection under Sect. 91, Fig. 1 (Cancelled) is shown an arrangement of a filter for A.G.C. voltages in which diode 5 conducts when the A.G.C. voltage exceeds a certain negative value so that capacitor 4 is effectively connected across the horizontal leads, thus increasing the time constant. Alternatively, the capacitor may be switched across the leads by a relay whose operating coil is connected in the cathode circuit of a controlled stage, as in Fig. 4 (Cancelled, not shown). The Specification as open to inspection also shows a circuit for A.F.C. in which the circuit of Fig. 1 (Cancelled) with the diode connections reversed may be used, the effect being that the time constant is reduced when the control voltage exceeds a certain negative value, Fig. 2 (Cancelled, not shown). When the diode forms parts of a multiple valve having a common cathode substantially at earth potential, as in Fig. 3 (Cancelled), the diode anode may be positively biassed through a resistor 11 to obtain the same effect. In this arrangement the control voltage is applied to the control grid of the main part of the valve so that the anode current suitably varies the value of an inductance by means of a saturation control winding. This subject-matter does not appear in the Specification as accepted.

Title: Magnetic antenna systems
IPC: H01Q7/00
Filed: 1958-11-04
Abstract: 842,246. Aerials; radio direction finding. LEAR Inc. Nov. 4, 1958 [Jan. 3, 1958], No. 35312/58. Class 40(7). An aerial comprises a thin slab of magnetic material 10, having a pair of flat and parallel faces, which is wound with a pair of windings 12, 14, Fig. 1, so disposed in relation to each other that the mutual inductance between them is small and preferably zero. As used in an aircraft direction finding system the aerial is sunk in a recess in the aircraft skin and is fixed in relation to the craft. The ends 26, 28 of winding 12 and 30, 32 of winding 14 are taken to the stator windings 35, 36 of a goniometer, Fig. 2. A receiver 46, fed from the rotor coil 44 of the goniometer, controls a motor 52 to drive the rotor to a null position. The aerial core always has a plane of symmetry perpendicular to its faces but its shape may be modified to compensate for quadrantal errors. The windings may be wound on such cores to cross each other at angles other than 90 degrees. Figs. 8, 9, 10 (not shown).

Title: Improvements in or relating to cooling devices for manipulating members for controlling heating apparatus communicating with flues
IPC: F24C3/12
Filed: 1960-10-14
Abstract: 916,906. Cooling gas heater control members. MAIN Ltd., R. & A., and FRANCIS, S. E. Oct. 3, 1961 [Oct. 14, 1960], No. 35323/60. Class 126. [Also in Group XIII] Cooling air is drawn past the control knob 33 of a gas heater by flue draught action. A gas cock 22 is controlled by the knob 33 which is mounted in a flanged opening 12 at the top and near the side of the heater. Opening 12 is connected to an opening 17 in the back of the heater by means of a channel 24, and the top panel 11 of the heater projects beyond the rear panel 14 so that when placed against a fire surround 16 the opening 17 in the heater is in communication with the fireplace chimney. The chimney draught causes air to be drawn past knob 33 which may be perforated to increase its surface area. Channel 12 may be cast as shown and held in place by screws 28 or may be manufactured of sheet metal and welded in place, see Figs. 3 and 4 (not shown). The gas heater illustrated is of the type in which room air circulates over a heat exchanger through which combustion products flow from a gas burner to an outlet 19.

Patent GB-1559117-A (GB)
Title: Method and apparatus for manufacture of mineral wool
IPC: D04H1/72
Filed: 1976-08-26
Abstract: Mineral wool is manufactured by a flow of a liquid melt being guided onto the circumferential surface of at least one rapidly rotating rotor. The melt first adheres to the surface of the rotor and is then thrown away from the surface in the form of threads. In this case, these threads are cooled by means of an air flow. The air flow is supplied in the circumferential region of the rotor in such a manner that it has both an axial as well as a tangential flow component in relation to the rotor. Provided close to the rotor (1) and along at least a part of its circumference is a slot (11) which runs concentrically with the rotor (1). Situated in this slot (11) are blades (8). Mineral wool which is manufactured in this manner has a considerably improved tensile strength. <IMAGE>
